Got my Raptor in 4/17. Programmed Home Link to my garage door opener with ease and has worked fine since. Lately, I've had to get closer and closer to the door for it to open, then it shut down. I've spent hours trying to reprogram it based on Ford's and Home Link's instructions, various videos and help from others. It still has power to the unit because the light blinks and my wife's Explorer Home Link will open the door. Has anyone had this problem and how was it fixed?
